Definitions

  • the radially-aligned bars provided between adjacent permanent magnets are embodied with a thin profile, the flux distribution between two adjacent permanent magnets or poles is reduced. It must merely be ensured that the bars are thick enough to deal with the mechanical stresses arising during operation.
  • FIG. 3 shows exemplary embodiments of the interconnection of the phase windings of the stator.
  • the three phase windings are connected to each other in a star configuration.
  • the three phase windings are interconnected in a triangular configuration.
